Hereinafter, embodiments of the present invention will be described indetail with reference to the accompanying drawings.

FIG. 1 is a plan view schematically showing an example of a touch screenpanel fabricated according to an embodiment of the present invention,and FIG. 2 is an enlarged view showing a part of an example of a sensingpattern shown in FIG. 1.

However, in FIG. 2, a sensing pattern connected to a sensing orconductive line and positioned at a side of an active area among sensingpatterns shown in FIG. 1 is shown for convenience.

Referring to FIG. 1 and FIG. 2, the touch screen panel according toembodiments of the present invention is configured to include: sensingpatterns 220 formed in an active area of a transparent substrate 10 andsensing or conductive lines 230 formed in an inactive region of thetransparent substrate 10 and connecting the sensing patterns 220 to anexternal driving circuit (not shown) through a pad unit 250.

The configuration of the touch screen panel according to embodiments ofthe present invention will be described below.

First, as shown in FIG. 2, the sensing patterns 220 includes a pluralityof first sensing cells 220 a formed to be connected in a row directionfor forming each row line, first connecting lines 220 a 1 connecting thefirst sensing cells 220 a to one another in the row direction, secondsensing cells 220 b formed to be connected in a column direction forforming each column line, and a second connecting lines 220 b 1connecting the second sensing cells 220 b to one another in the columndirection.

In embodiments, a sensing cell 220 a′ among the first sensing cell 220 ais positioned at a the right side of the active area, implemented in atriangular shape and electrically connected to the sensing line 230formed in the inactive area.

Likewise, a sensing cell 220 b′ among the second sensing cells 220 b ispositioned at a bottom end of the right of the active area, implementedin a triangular shape and electrically connected to the sensing line 230formed in the inactive area.

However, the first and second sensing cells 220 a and 220 b other thansensing cells 220 a′ and 220 b′ formed at the top, bottom, right andleft sides of the active region are implemented in a diamond shape.

The first and second sensing cells 220 a and 220 b are alternativelydisposed so as not to be overlapped with each other, and the first andsecond connecting lines 220 a 1 and 220 b 1 intersect with each other.Here, an island-shaped insulating layer 240 is interposed between thefirst and second connecting lines 220 a 1 and 220 b 1 in order toprovide insulation between two connecting lines and stability.

In embodiments, the first and second sensing cells 220 a and 220 b maybe formed integrally with the first and second connecting lines 220 a 1and 220 b 1 using a transparent conductive material such as indium tinoxide (ITO), or be formed separately from the first and secondconnecting lines 220 a 1 and 220 b 1 and then electrically connected toone another by forming the first and second connecting lines 220 a 1 and220 b 1.

In embodiments, the second sensing cells 220 b may be formed integrallywith the second connection lines 220 b 1 in the column direction, andthe first sensing cells 220 a may be patterned between the secondsensing cells 220 b so as to each have an independent pattern and beconnected to each other by the first connecting lines 220 a 1 in the rowdirection.

According to embodiments of the present invention illustrated in thedrawings, the first connecting lines 220 a 1 are formed on theisland-shaped insulating layer 240 to connect first sensing cells 220 ato one another. However, the present invention is not necessarilylimited thereto.

In embodiments, each of the first connecting lines 220 a 1 may directlycontact two immediately neighboring cells among the first sensing cells220 a at an upper or lower portion of the two immediately neighboringfirst sensing cells 220 a to thereby electrically connect them. In otherembodiments, each of the first connecting lines may be electricallyconnected to the first sensing cells 220 a through contact holes, or thelike, formed through an insulating layer (not shown) formed throughoutthe substrate.

Further, the first connecting lines 220 a 1 may be made of a transparentconductive material such as ITO or be made of an opaque low resistancemetal material, and have an adjusted width, or the like, in order toprevent visualization of the pattern.

However, the case in which the first connecting lines 220 a 1 are madeof the same material as that of the sensing lines 230 is described byway of example in embodiments of the present invention.

The sensing lines 230 are connected to the first sensing cells 220 a ina row unit and the second sensing cells 220 b in a column unit toconnect the first and second cells 220 a and 220 b to the externaldriving circuit (not shown) such as a position detecting circuit throughthe pad unit 250.

These sensing lines 230, which are disposed in the inactive area thatcorresponds to the outside of the active area in which an image isdisplayed, may be made of a wide range of materials. That is, thesensing lines 230 may be made of a low resistance metal material such asmolybdenum (Mo), silver (Ag), titanium (Ti), copper (Cu), aluminum (Al),molybdenum/aluminum/molybdenum (Mo/Al/Mo), and the like, in addition tothe transparent conductive material used to form the sensing patterns220.

The touch screen panel according to embodiments of the present inventionas described above is a capacitive type touch panel. When a contactobject such as a human hand, a stylus pen, or the like, contacts thetouch panel, capacitance change at the contact position is transferredfrom the sensing patterns 220 to the driving circuit (not shown) via thesensing lines 230 and the pad unit 250. In this case, the change incapacitance is converted into an electrical signal by an X and Y inputprocessing circuits (not shown), or the like, such that the contactposition is recognized.

According to an comparative example, the photolithography process can beused in order to fabricate the touch screen panel shown in FIGS. 1 and2. However, as described above, in the case of forming sensing patterns,and the like, through the photolithographic process, a process iscomplicated and a fabricating cost is significantly high.

In another comparative example, a method of fabricating the sensingpatterns, and the like, in a printing scheme is introduced. However, inthe case in which an existing printing scheme is used, the sensingpatterns, the sensing lines, and the insulating layers are formedthrough different steps or processes, respectively, which istroublesome.

Therefore, according to embodiments of the present invention, componentsof the sensing patterns, the insulating layers, and the sensing linesare formed on the transparent substrate in an offset printing scheme. Inembodiments, print solutions (which can also be referred to as printingmaterials, printing compositions, or materials to be applied) areimplemented as materials for forming the respective components areformed in different areas particularly on an outer surface of a blanketroll, thereby making it possible to reduce costs required for a mask andthe number of processes of the existing photolithographic process.

An apparatus and method of fabricating a touch screen panel according toembodiments of the present invention will be described in more detail.

A target of the apparatus of fabricating a touch screen panel accordingto embodiments of the present invention is a printing apparatus formingthe components such as sensing patterns, and the like, included in thetouch screen panel. Here, although a printing method using the printingapparatus may be implemented in various schemes, a fabricating apparatusand method of implementing an offset printing process will be describedas by way of example in embodiments of the present invention.

In embodiments, the offset printing process includes forming patternmaterials as patterned, printing materials on the outer surface of theblanket roll and subsequently transferring the pattern materials to thesubstrate. The blanket serves as an intermediating apparatus which isused rather than printing the pattern materials directly on thesubstrate, such that electrodes are printed to have a more accuratewidth, thereby making it possible to obtain more definite image quality.

However, this is only an example, and embodiments of the presentinvention is not necessarily limited thereto.

FIGS. 3A and 3B are views showing a schematic configuration of anapparatus of a fabricating touch screen panel according to embodimentsof the present invention.

Referring to FIGS. 3A and 3B, the apparatus of fabricating a touchscreen panel according to embodiments of the present invention isimplemented as a gravure offset printing apparatus. The gravure offsetprinting apparatus includes a substrate support 110 supporting asubstrate 10 thereon, a gravure roll 112 disposed at or adjacent one endof the substrate support 100 and having materials applied to an outersurface thereof, a blanket roll 122 provided so as to be capable ofapproaching and becoming distant from the gravure roll 112 and receivingthe materials from the gravure roll 112 to re-transfer the materials tothe substrate on the substrate support 110, and a blanket roll drivingunit 132 rotating and horizontally driving the blanket roll 122.

The gravure roll 112 serves to transfer the respective materialscorresponding to the sensing patterns, the insulating layers, and thesensing lines shown in FIG. 1 and FIG. 2, which are materials forprinting, to different areas on the outer surface of the blanket roll122.

According to embodiments of the present invention, a transparentconductive material corresponding to the sensing patterns, an insulatingmaterial corresponding to the insulating layers, and a metal materialcorresponding to the sensing lines are implemented as differentmaterials.

In embodiments, the gravure roll 112 and the blanket roll 122 havesubstantially the same volume. The gravure roll 112 may rotate at acorresponding position by a gravure roll driving unit (not shown)coupled to a supporting unit 152 fixed to and stood-up at each of bothends of a lower base 140. The gravure roll 112 may be coupled directlyto the gravure roll driving unit, or be coupled to the gravure rolldriving unit through a separate pocket (not shown). In the case in whichthe pocket is provided, the gravure roll 112 may be easily replaced, andeccentricity and the horizontal axis line of the gravure roll 112 may beeasily adjusted.

Dispensers 162 applying the materials to the outer surface of thegravure roll 112 apply each of materials corresponding to the sensingpatterns, the insulating layers, and the sensing lines of the touchscreen panel described above to the outer surface of the gravure roll112. Therefore, according to embodiments of the present invention, thenumber of dispensers is three so as to correspond to that of thematerials.

Meanwhile, the outer surface of the gravure roll 112 is divided intothree areas corresponding to the number of materials, and at least onedifferent prominence-depression pattern is formed in each area as shownin the enlarged portion A of FIG. 3A. Here, the prominence-depressionpattern may have a relief shape or intaglio shape. When the pattern hasthe relief shape, the material is applied to an outer surface of aprominent portion (not shown) of the prominence-depression to thereby betransferred to the blanket roll 122. When the pattern has the intaglioshape, the material is applied to an inner portion of a depressedportion 112 a to thereby be transferred to the blanket roll 122.

However, it may be advantageous that the prominence-depression patternformed on the outer surface of the gravure roll 112 has the intaglioshape in order to keep the thickness of the material pattern uniformwhen blanket roll 122 forms the material patterns by receiving thematerial transferred from the outer surface of the gravure roll 112 andretransferring (printing) the material to the substrate 10.

When each of three different materials is applied to the correspondingouter surface among the three areas of the gravure roll 112 separatedfrom each other by the dispensers 162, the material need to besubstantially applied only to the depressed portion 112 a as shown in anenlarged portion B of FIG. 3A. However, when the dispensers 162 applythe materials to the outer surface of the gravure roll 112, it isdifficult to apply the materials at a time such that the materials areselectively received only in the depressed portion 112 a of the intaglioshape.

Therefore, the dispensers 162 apply the materials so as to be widelyspread over the entire outer surface of the gravure roll 112 when theyapply the materials to the outer surface of the gravure roll 112 andremove unnecessary materials applied to a surface 112 b with theexception of the depressed portion 112 a having the intaglio shape afterthe application is completed, thereby making it possible to allow thematerials to be received only in the depressed portion. To this end, adoctor blade 172 is provided around the gravure roll 112 in order toremove the unnecessary materials.

The doctor blade 172 includes a knife holder 172 b and a knife 172 acoupled to the knife holder 172 b, wherein the knife 172 a is disposedin parallel with a length direction of the gravure roll 112 to removethe material while contacting (the knife 172 may be actually spacedapart from the surface of the gravure roll 112 by a slight interval) thesurface of the gravure roll 112 rotating in the state in which thematerials are applied.

As described above, since the front end of the knife 172 a contacts theouter surface of the gravure roll 112, when the materials are applied tothe rotating outer surface of the rotating gravure roll 112, thematerials applied to the surface 112 b with the exception of thedepressed portion 112 a having the intaglio shape may be naturallyremoved by the knife 172 a. As a result, the materials may be receivedonly in the depressed portion 112 a as shown in the enlarged portion Bof FIG. 3A.

Further, the blanket roll 122 according to embodiments of the presentinvention receives the material pattern formed on the region of theouter surface corresponding to each of three areas of the gravure roll112 separated from each other and then moves to the substrate support100 to substantially serve to print each material pattern on thesubstrate.

That is, the illustrated embodiment of the present invention isimplemented so that the outer surface of one blanket roll is dividedinto a plurality of areas and the material pattern corresponding to eachcomponent is transferred to each area.

Therefore, as shown in FIG. 3A, the outer surface of the blanket roll122 according to embodiments of the present invention is divided intothree different areas 310, 320, 330, wherein a first material pattern312 containing a transparent conductive material for forming the sensingpatterns are transferred to a first area 310, a second material pattern322 containing an insulating material for forming the insulating layersare transferred to a second area 320, and a third material pattern 332containing a metal material corresponding to the sensing lines aretransferred to a third area 330.

In embodiments, the blanket roll 122 is capable of approaching andbecoming distant from the gravure roll 112, and rotating on the uppersurface of the substrate 10 loaded on the substrate support 100. To thisend, both sides of the blanket roll 122 are provided with the blanketroll driving unit 132 so as to move the blanket roll 122 on a side railR of the lower base 140 in the horizontal direction and rotate theblanket roll 122 at a corresponding position, as shown in FIG. 3B. Theblanket roll driving unit 132 rotates and horizontally drives theblanket roll 122 so as to print a plurality of different materialpatterns transferred from the gravure roll 112 on the substrate as theyare. Therefore, according to embodiments of the present invention, theblanket roll driving unit includes a rotational driving unit 132 a and ahorizontal driving unit 132 b.

With the apparatus according to embodiments of the present inventionshown in FIG. 3A and FIG. 3B, in forming components such as the sensingpatterns, the insulating layers, and the sensing lines on the substratein the offset printing scheme, print solutions (printing materials)corresponding to the materials corresponding to the respectivecomponents are formed in three different areas 310, 320, 330 of a singleblanket roll 112, thereby making it possible to reduce a cost requiredfor a mask and the number of processes compared to the existingphotolithographic process. A method of fabricating a touch screen panelaccording to embodiments of the present invention will be describedbelow in more detail.

After the first and second sensing cells and the second connecting linesare formed by printing the first material pattern 312, the secondmaterial pattern 322 formed in the second area 320 of the outer surfaceof the blanket roll 122 are printed in the active area of the substrate10 by rotating and moving the blanket roll 122, as shown in FIG. 4B.

That is, referring to an enlarged plan view of a partial area of thetouch screen panel shown in FIG. 4C, the third material pattern 332corresponds to the first connecting lines 220 a 1 electricallyconnecting adjacent first sensing cells to each other and sensing lines330 formed in the inactive area and connected to the first sensing sells220 a 1 in the row unit and the second sensing cells 220 b′ in thecolumn unit.

As described above, according to embodiments of the present invention, asingle blanket roll 122 is used thereby making it possible tosimultaneously form sensing patterns 220, the insulating layers 240, andsensing lines 230.
